Transport of water in soft confinement: influence of surface chemistry, hydrostaticpressure and mechanical stress.
Transport of water in soft porous materials is relevant to a broad range of applications but remains unclear in many aspects because of several effects that have to be taken into account: surface chemistry, diffuse boundaries and deformations or mechanical effects. In the proposed study, we plan to experimentally investigate the interplay between mechanical deformation, structure and transport. On the two selected samples (PIM, Intrinsic Microporosity Polymer), we will first characterize the structure and porosity of the films, in dry and hydrated states. And, in a second step, follow their structural evolution at different hydrostatic pressures and mechanical stresses. For this purpose, we require 5 days on D16.
